Thanks for all the responses guys, much appreciated. I'm def going to get the two testers.
jafofubar57 - I'm also using foxfarm nutrients, happy that you've had such good results with it, makes me much more confident.
Mr. Grow It - Another curiosity about the ppms, lets say the medium is lacking in one specific nutrients, wether its N, P, K, Cal or Mag. How do you know which one it needs so that you're not overfeeding it either one. Does the TDS differentiate specifics or just give a one number reading?
Also with your cheat sheets that you have in the beginner guide, you have ranges for temp as an example for certain periods of time. So if one of your ranges is 20-40 of anything for example, is it a good rule of thumb to aim for the middle, so 30 in this example?
growhouse262 - I'll link to the Australian hardware store site which has the medium I'm using, I also took a picture of the back of the bag in nice high quality so you can zoom to read, because for some reason putting the back of the bag on the site was too hard :P
